This invention relates to new and useful improvements in side sills for freight cars, principally the hopper type of freight cars whose sides are spacedthe maximum distance 5 permitted rby railroad clearance lines. The resent application is for a reissue of Patent o. 1,703,804, the application for which was a division o f the application which eventuated in Patent No. 1,703,756, dated February 26,

A primary object of the invention is to provide a side sill of novel form and maximum strength'which ma be easily manufactured and associated wit adjoining parts of the 16 car construction. a"

A principal feature of the invention consists in constructing a side sill from an angle shaped member which is formed'so as to'be of substantially Z shape intermediate its ends. 20 Another feature ofthe invention consists in providing the end portions of the side sill with legs'or flanges' adapted to be 'secured to the bolsters and in providing inter-r mediate portions of the sill with substantially vertical s 'aced legs or flanges to which the lower en s of the car side sheets and the upper endsof the outer hopper side sheets may be respectively fastened.

AAnother feature of the invention resides 3 in providing aportion of the side sill with a `downwardly and inwardly inclined web.

Other and-` more specific features of the invention residing in advantageous forms, 4combinations and relations-of parts will hereinafter appear and be pointed out in the claims. v i

In the drawings illustrating a preferred .embodiment of the invention:

Figure 1 is a diagrammatic-plan view of a hopper car of the maximum'width type embodying t-he invention. Figure 2 is a diagrammatic side elevational view of thevcar illustrated in -Figure 1.

4Figure 3 is a fragmentary-side elevational view adjacent one end of the car..

Figure 4 is an enlarged sectional view taken on line 4 4, Figure 3.

Figure 5 is an enlarged sectionalview taken 0n line 5A-5,Figure` 3.

The side'stakes 10'and 10 which roject inwardly Abeyond the side sheets of t e car are preferably of Z shape, one flange of each bein secured to the inner face ofthe associated si e sheet. The side stakes l0a're secured to the bolsters 1.1, which may be of any suitable construction, while the side stakes 10* are spaced along thev car sides intermediate the holsters.

As it is necessary to attach appurtenances, such as ladders and grabirone, tothe sides of the car adjacent its ends the construction at the ends must be such that these appurte- 'Il nances will not roject beyond the limits defined byA the si esheets, which are spaced apart a maximum distance. .To accomplish this result the ends of the car are reduced or restricted and the-end side sheets 8 converge inwardly from the ad'acent side stakes 10 to the end'sof the car, eing secured at these points to the car corner posts 12.' The slope sheets 34 extend downwardly from ,the ends of the car toward the center 'thereof and .each 85 may advantageously be secured to adjacent `side sheets by the angle members designated A and B, respectively. The angle A is emplo ed for connectin the slope sheets to the endy side sheets 8, w ile the angle vB is employed for connecting the slope sheets to the main 4side sheets 3. U

Extending continuously betweenthe bolsters are the main side sills 15. Each of these V side sills preferably terminates at the bolsters,

. because should they. extend continuously to the ends of the car it would be necessary to incline their ends inwardly to conform to the convergence of the end side sheets 8. How

ever, extendingbetweenthe-bolsters and the V uoY car ends are auxiliary side sills 16 of angle shape. WVhile these sills are connected directly to the end structure of the car, they are connected to the holsters and side sills through the intermediacy of bracket members 17. Thus, on each side of the car isa main sill 15 and two auxiliary sills 16 the latter being spaced inwardly a suitable distance from the former to extend parallel thereto and be connected to the restricted ends of the car. l

Each side sill is formed with portions for attachment to the body holsters 11, each of these portions comprising an upwardly extending leg or flange 51 adapted to be secured to one side or end of the adjoining bolster and an inwardly extending leg or flange 52 adapted to be secured to the under side or bottom of the bolster. These legs or flanges are preferably disposed at right anglesV to each other and the upright leg' 51 is so arranged that the outer flange of the adjacent side stake 10 may be interposed between itfand the bolster, as clearly shown in Figure 6.

Intermediate the bolster attaching portions, the side sill is of substantially Z shape, havino oppositely extending, preferably vertical, 'Iegs or flanges 51a andv52a connected by a downwardly inclined web 55. This Z 'shaped portion of the sill may conveniently extend continuously between the pointswhere the planes of the slope sheets 34 at opposite ends of the car respectively intersect the sill.

From these points to points respectively adjacent the holsters the Z portion of the siill changes in formation, gradually merging into the angle shaped endv portions. Thus, from the points where the planes of the slope sheets intersect the side sill to points adjacent the bolsters, the upwardly extending flange 51I ofthe Z gradually increases in height, while the inclined web 55 and the downwardly extending leg 52 gradually decrease in width and depth until these portions respectively merge with the angular portions of the sills.

In the portions `of the sill where it changes from Z-shape to angle shape the inclined web 55 and the leg 52'* are separated by a horizontal portion 52 ywhich constitutes a continuation of the horizontal flange 52 and which decreases inwidth as the web increases connecting them froni the side sill, this may be done without disturbing the connection between the sill and the side sheets 3. Furthermore, since fewer `rivets are required to connect the hopper sheets to the sill than toV connect the car side sheets thereto, not only does this construction of sill eliminate the necessity of disturbing the connection betweenthe sill and car side sheets, but replacement of the hopper side sheets may be more expeditiously accomplished. It will also be appreciated that by providing the sill with oppositely projecting car side sheet and hopperside sheet attaclnng flanges, off-setting or anging the-sheets to efect their lconnection to the sill is made unnecessary.

By connecting the oppositely extending legs or flanges of the Z portion'of the sill by an inclined web the interior of the car is provided with a transversely inclined surface which eatly facilitates the discharge of lading rom the hopper through the hopper doors.

From the foregoing it will be perceived that the construction of the side-sill is such that it may be conveniently and readily secured to the bolsters and that the car side sheets and hopper side sheets ma be attached to separate portions thereo so that the latter may be readily replaced. Furthermore, the inclined web of the vside sill reatly facilitates `the discharge of lading tlgirough the hopper doors of the car. Althou h the side sill disclosed is particularly app icable to cars of maximum width and, therefore, to those having reduced ends as the hopper side sheet attaching flange of the sill isdi'sposed inwardly of the car side sheet attaching flangeand no portion of the sill projects outwardly beyond the car sides, it will be appreciated that its utility is not solely limlted to cars of this particular type.
